T‑tube versus internal drainage tube in laparoscopic common bile duct exploration.

The 203 patients who underwent laparoscopic common bile duct exploration for choledocholithiasis were retrospectively analyzed. The patients were divided into internal drainage tube group (n=87) and T-tube group (n=116). Total bilirubin, direct bilirubin, alanine aminotransferase (AST), aspartate aminotransferase (ALT), the diameter of common bile duct, number of stones, operation time, intraoperative bleeding, postoperative hospital stay and postoperative complications were compared between the two groups.

Application of intraoperative navigation in 3D laparoscopic pancreaticoduodenectomy: A case report.

Laparoscopic pancreaticoduodenectomy is one of the most challenging operations in abdominal surgery, with a high risk and numerous potential complications. Laparoscopy can magnify the surgical field, improving vision, but it cannot see through and identify the internal structures of the surgical field. Intraoperative navigation is a technology currently being developed; it projects the three-dimensional (3D) image established before surgery onto the surgical area during surgery, locates the anatomical landmarks, matches the 3D image with the actual image, and then displays the relationship between the tumor and the surrounding blood vessels.

Application of an internal drainage tube in laparoscopic common bile duct exploration.

Choledocholithiasis is a common disease of the biliary system. The traditional surgical method for this is to remove the gallbladder, open the common bile duct, remove the stones and place a T-tube in the common bile duct for drainage. Common bile duct exploration usually requires a T-tube.

Overexpression of the Survivin gene in SGC7901 cell resistance to cisplatin.

The aim of the present study was to investigate the mechanism of SGC7901 cell resistance to cisplatin (CDDP). SGC7901/CDDP cells were established by the long-term continuous exposure of SGC7901 cells to CDDP in stepwise concentration increments. The morphologies of the SGC7901/CDDP and SGC7901 cells were observed by microscopy.

The effects of aspirin plus cisplatin on SGC7901/CDDP cells .

The purpose of this study was to determine the effect of aspirin plus cisplatin (CDDP) in the chemotherapy of gastric cancer. We cultured SGC7901/CDDP cells by long-term exposure of SGC7901 cells to small doses of CDDP . The cells were treated with aspirin, CDDP or aspirin plus CDDP for 24 h and cell growth was assessed by the MTT assay, the apoptotic rate by flow cytometry, the survivin mRNA expression by RT-PCR and the survivin protein expression by western blotting.

[Expression and clinical significance of secretory leucocyte protease inhibitor in colon carcinoma].

Objective: To investigate the expression of secretory leucocyte protease inhibitor (SLPI) in colon cancer and their clinical significance.

Methods: Immunohistochemistry was performed to detect the SLPI expression in colon cancer tissue microarray. The expression of SLPI was scored by two pathologists and was analyzed using Χ(2) test to explore its influence on the pathologic characteristics of colon carcinoma.

The association between the survivin C-31G polymorphism and gastric cancer risk in a Chinese population.

Introduction: The C-31G polymorphism in the survivin promoter could de-repress the cell-cycle-dependent transcription of the human survivin gene, resulting in overexpression of survivin. This survivin mutation has only been studied on cervical carcinoma. However, no study has ever been conducted to evaluate the effect of the polymorphism on other cancers, including gastric cancer.
